Already I am having big doubts. When Rylan mentioned that they have a good mix lined up, a part of me was enthusiastic, but looking at the housemates, there doesn't seem to be much of a 'good mix' I will reserve judgement until at least a week, but already the show seems to be continuing to head down the wrong path!
My current doubts are
The housemates: They look like they belong to The Apprentice and not one of them really stands out, they all appear self-absorbed
Past housemates entering the house: This was covered in BB10 and it worked because it coincided with the 10th anniversary! Throwing former housemates back in again (even if just for a task) just reeks of desperation! I sincerely we see no C4 housemates going back in for a fleeting visit because to me - that would be an insult to the show's legacy by having legends grace the new tacky version of Big Brother
Rylan: Why on earth is he having so much coverage? He's in the flaming adverts for pity sake... It that doesn't make the show look even more cheap, I don't know what does
But surely it can't be any worse than BB15, can it?

They won't be reappearing for the long haul. No confirmation has been given to back this up, but I think it's obvious that they'll be part of a time-based task...
